So again, I think the original author is being a bit of an alarmist
because the solar wind/heliosphere does not give us -that- much
protection. Now if you want to worry, worry about the strength of our
magnetosphere going low. :-)


Which some scientists say is overdue (a polarity shift/switch). This has
supposedly happened at least one other time since life appeared on Earth, so
it wouldn't be an extinction level event.. but would sure mess things up for
a few hundred to a few thousand years.
